...backlight images from the canvases to try to compare with the x ray images...
...did the Masters use canvas from the same bolt or roll for their paintings ?
...answering the question in technical painting research is becoming more and more in the picture.
I am writing a document about my experience and knowledge on hand weaving reconstructions of painters canvas.
These pictures are the first backlight shots of the canvas to try to compare the x ray images with the real textile images...
note: grouping of the warp threads is result of the reed I am using in the weaving.
Please let me know if you want to know more details already...
